Purpose The purpose of this study was to investigate the effects of training methods on body composition, isokinetic strength and muscle endurance, cardiopulmonary function, and anaerobic power in female judo players. Methods Subjects performed weight training (n=10) and circuit weight training (n=10) consisting of 10 sports items for 12 weeks. In order to analyze the effects of training, body composition, isokinetic strength and muscle endurance, cardiopulmonary function, and anaerobic power were measured and the effect of training was verified. Results First, the comparison of body composition between WT and CWT groups showed that significant interaction effect between group and period was found in all variables (weight: F=1082.694, p=.001, body fat mass F=199.999, p=.001; skeletal muscle mass F=2481.698, p=.001, and percentage body fat: F=496.246, p=.001). Second, there was a significant interaction effect between group and duration in shoulder muscle strength and knee endurance (EPTL: F=6.598, p=.019; EAPL: F=12.860, p=.002). Conclusions The result of this study showed that the interaction effect between period and group was not significant according to the training method but the overall effect of the circuit weight training group was more positive than the weight training group. Therefore, it can be concluded that the 12 weeks circuit weight training can contribute to improve the performance of female Judo players by improving body composition, strength and muscle endurance, cardiopulmonary function and anaerobic power.
Purpose The purpose of this study was to establish the differences of anticipating accuracy and confidence according to fencing expertise and spatial occlusion region. Methods For the purpose of this study, the anticipation ability of 6 high-level fencing players and 6 low-level fencing players were analyzed. All subjects performed the 60 tasks of anticipating the attack positions(thorax, thigh, toe) from observing the fencing video screen using spatial occlusion technique. The spatial occlusion technique was used in 6 particular body of opponent’s movement. For statistic analysis, data was analyzed through independent T-test measure. Moreover, Paired t-test were used as follow-up analysis. Results The results of the study were as follows: In terms of accuracy anticipation, the main effect of expertise was significantly different. Specifically, when the spatial occlusion technique was applied in head, left leg, arm, and a foil, the accuracy of anticipation was significantly different. Moreover, comparing with no-occlusion condition, anticipation accuracy decreased when spatial occlusion technique was applied in arm and foil. In terms of confidence, there was no significant difference between level of expertise. Conclusions In order to effectively anticipate the opponent’s movement in fencing sports, it is necessary to focus on the visual cues of arm/shoulder, and the foil. Especially, focusing on the foil movement might provide the core informations on anticipation ability.
Purpose The purpose of this study was to develop a comprehensive model for facilitating and hindering factors about girls' participation in physical activities. Methods Based on systematic analysis, 26 foreign journals published from 2005 to 2016 were comprehensively analyzed. The journals were directed to facilitating and hindering factors of girls' physical activities. A model was developed by categorizing various factors in the previous studies, and by conceptualizing those categories, and by creating visualization of relations between the categories. Results Seven facilitating factors are referred to as 'SPORTS', including ‘Self-recognition’, ‘Physical environment’, ‘Opportunities’, ‘Relationship’, ‘Treatment’, and ‘Social supports’. In contrast, nine hindering factors are conceptualized as 'INCAPABLE' which includes 'Internalized gazes’, ‘Negative feedback’, ‘Competitiveness’, ‘Alternativeness’, ‘Perceived danger’, ‘Appearance’, ‘Bad feeling’, ‘Lack of opportunities’, and ‘Effeminate norms'. Conclusions It is suggested that the girls' physical activity patterns vary depending on whether the girls subjectively interpret the physical activity or girls are being objectified by other's evaluation. And those individual, relational, and environmental levels are needed to strengthen the subjectification of girls.
Purpose This purpose of this study was to understand how physical education can contribute to healthy emotions and activities of human beings. Methods We analyze Eva Illouz's emotional capitalism theory, the position and role of emotions in Spinoza, and Durkheim's theory of religious sociology. Results Illouz shows that emotions are coordinated by rationality through the analysis of emotional capitalism, and that expressions of natural emotions are restricted and controlled even in the area of intimacy. In Spinoza, emotions are divided into three emotions: joy, sadness, and desire as concepts of body movements. Emotions reveal that they are closely related to human activity, and emotions of joy are calculated for human emotional development Emphasize the need to organize meetings of possible bodies. Durkheim argues that while society is placed in a religious position, society is the subject of individual praise and the reality of baptizing individuals into morality. At this time, festivals and rituals reveal individuals to be a powerful mechanism that leads to devotion to society and strengthens individual’s sense of community and morality. Conclusions Making physical education classes as festivals enhances students' sense of community. It can also be an activity that allows students to have healthy moral and emotional energy.

[Purpose] The purpose of this study was to examine the effect of recovery methods comparing with change ratio in Lactic acid(LA), Heart rate(HR), VAS(Visual analogue scale) on recovery patterns after field training(FT) in Korea National bobsleigh and skeleton players. [Methods] The tests were conducted for 3 times at a one-week interval as an experimental design within the same subjects(n=9), observed change ratio in LA, HR, VAS through applying Active recovery(AR), Whole body vibration(WBV) & Cold water immersion(CWI) after FT. [Results] The results were summarized as follows: The alteration of ratio in LA, HR, VAS decreased significantly after applying the three recovery patterns(p<.01). The difference between the groups showed that the reduction in lactic acid according to active recovery and whole-body vibration was higher than cold water immersion(p<.01). [Conclusion] In conclusion, although active recovery was more effective than static recovery, there was a significant effect of the three recovery methods in this study on reducing a fatigue in bobsleigh & skeleton players. Therefore, it would be considered to improve the performance of athletes when these methods apply for them depending on situations and environments.
Purpose The purpose of this study was to investigate the changes of gait patterns and muscle activations according to dual tasks during stair ascending. Methods Twelve sedentary young male adults(Age: 27.0±1.8 yrs, Weight: 65.8±9.9 kg) without any lower extremity injuries participated in the study. Participants performed stair walking up 7 floors and their ascending motion on each floor was analyzed according to dual tasks. A wireless electromyography (EMG) were attached on the Rectus Femoris(RF), Biceps Femoris(BF), Gastrocnemius(GN), Tibialis Anterior(TA) muscle to calculate integrated EMG(iEMG) and co-contraction index(CI). Chest and left heel accelerometer signal were recorded by wireless accelerometer and those were used to calculate approximate entropy(ApEn) for analyzing gait pattern. All analyses were performed with SPSS 21.0 and for repeated measured ANOVA and Post-hoc was LSD. Results The results of this study indicated that dual task appeared to increase their time, CI and there were a statistically significant difference in most muscle on each floors compared to the non dual tasks. Also, ApEn were a statistically significant difference in only left and right direction than non dual task. Subjects showed more irregular pattern and instability muscle activation response during dual tasks. Conclusion Because there are many dangers often use of stairs in everyday life, in the future, we have to make a lot of efforts to prevent fall.
